Abstract: An organic salt having an alkali metal bound to a disubstituted amide of alkane iminosulfinic acid has the following general formula: where Ar is an aromatic group, M is an alkali metal such as Li, K or Na, and CxHy is an alkane. The organic salt can be used to form non-aqueous liquid and gel or plasticized polymer electrolytes. The electrolytes can be used to form improved lithium and lithium ion batteries.
